How Vortex Exhaust Technology Works

Exhaust back pressure is a result of the engine’s inability to force toxic gases out of the combustion cylinder and away from the engine efficiently. Pulse waves, pressure waves and extremely hot gas, clashing with dense cool air, result in volatile conditions and temperatures of 800°C to 1100°C, causing a serious loss of engine efficiency.

The results of back pressure on a conventional exhaust system

In the combustion chamber gas leak-back and back pressure causes:

Incomplete fuel combustion

Serious loss in fresh charge (air / fuel mixture)

High gas temperature

High emissions

Loss of engine efficiency

High engine stress

The Negative Effects of Backpressure

Only one of the four engine cycles produce power, with the other three consuming power. Back pressure results in losses of 10 – 30% of engine efficiency and increased toxic emissions.

There are additional factors which add to back pressure build-up in an exhaust system including; catalytic converters, diesel particulate filters and silencers. These additional exhaust systems can reduce emissions and pulse waves but restrict the gas flow and cause backward pressure waves which all have a negative effect on engine efficiency.

This loss in efficiency results in:

Turbo lag

Loss of MPG of over 10%

Reduced engine BHP

Loss in engine torque

Increased toxic emissions

Reduced engine life

Limitations to Engine Efficiency

Volumetric Efficiency

Vortex’s patented exhaust technology centres on improving Volumetric Efficiency (VE), which is the ability to move charge (air) into, and exhaust gas out of, the cylinders. VE is the key to greater engine efficiency, i.e. a more complete combustion, resulting in more power, lower emissions and improved MPG.

Closed loop self-educating ECUs adjust their parameters to ensure that a more complete combustion is taken advantage of. Consequently, tuners can take full advantage of air first and then fuel to achieve ultimate combustion. Furthermore, turbo-chargers operating in low back pressure environments lose their lag and rev to a higher velocity, significantly improving performance.

Traditional methods to reduce back pressure

Headers

Tuned secondary primary pipes

De-cat pipes

Variable cam timing

Dump values

Bigger Exhaust pipe

Straight through systems and silencers

Cross over pipes

Exhaust wrapping

Thermal coatings

All of the above achieve, at best, only minor varied improvements in reducing back pressure. However, with all these technologies the engine is still working hard to force the gas out of the system against the same amount of drag, therefore significant back pressure is still present.

Vortex is the ONLY exhaust technology available that effectively eliminates back pressure, improving engine efficiency, boosting power and cutting emissions.

Vortex Exhaust Technology – the solution to negate back pressure

Vortex’s patented exhaust technology uses wasted energy, in the form of exhaust pressure, to accelerate gas over a profiled shape, creating a vortex. Acceleration of the gas flow creates low pressure in front of the vortex, resulting in a vacuum effect. This low pressure allows the engine to evacuate exhaust gases efficiently in front of the vortex and acceleration of gas behind.

The effect of scavenging the exhaust gases in front of the vortex allows the engine to breathe freely with little or no gas leakage back in to the combustion chamber, allowing cleaner air into the cylinder for more complete combustion. The spiralling acceleration of gas out of the system ensures no further build-up of back pressure occurs, resulting in:

More power

More torque

More MPG

Reduced emissions

Reduced engine stress

Reduced turbo lag

Additional benefits include:

Longer catalyst life

Longer DPF life

Increased service intervals

Less carbon build up

Longer engine life

Improved heat dissipation

Importantly, there are NO negative effects at all

A solution to significantly reduce emissions

The battle to reduce emissions

Ever increasing legislation has forced vehicle manufacturers to reduce the emission of harmful by-products of fuel combustion. Consequently, exhaust systems have become more complex in their design and more restrictive to gas flow, thereby reducing vehicle performance and power.

Vortex products are unique and have created a new generation of exhaust technologies that improve volumetric efficiency, resulting in significant emissions reductions and improvements to fuel consumption and performance.

Importance of Vortex Technology to Reduce Toxic Emissions

It is widely accepted that we should all be seeking ways to minimise the emissions of internal combustion engines and the effects on people and the environment. Vortex Exhaust Technology provides a practical and significant solution to significantly reduce emissions.

SECAMB Case Study

Case Study – SECAMB

South East Coast Ambulance Service

December 2013

As part of Vortex’s fleet development strategy for 2013, we approached South East Coast Ambulance Service to organise a trial study on how the Vortex® technology could enhance the performance characteristics of the ambulance vehicles.

The study was to focus on two main areas:

Fuel savings

Emissions reductions

After initial consultation, an agreed trial included 10 vehicles made up from;

1 x Landrover Discovery

2 x Patient Transfer Vehicles

3 x Volvo V50’s

4 x Mercedes-Benz Duel Manned Ambulances

Emissions Reductions

The results above show a 57% decrease in emissions following the fitting of a Vortex® exhaust system. Smoke temperature has also risen by 10+ ºC.

In addition, the Vortex® exhaust system that was fitted on this vehicle has totally eliminated diesel particulates large enough to be registered on the testing equipment.

Fuel Savings

SECAMB monitored the fuel usage of every vehicle in the test and compared figures to placebo vehicles and previous fuel consumption.

Significant fuel savings were recorded on every vehicle in the test, ranging from 6.73% improvement in the DMA vehicles up to an impressive 21.04% in the Volvo V50 and 25.88% in the Land Rover Discovery.

Full, conclusive figures are available from Vortex and SECAMB on request.
